Study and Application of Mine Low Temperature Thermal Resources Utilization Technology

According to the large and regenerated features of the low temperature thermal source reserves, based on the analysis on the uillization status of the lo W temperatures thermal sources at home and abroad, the paper pointed out the advantages and problems existed in the utilization of the mine low temperature thermal sources.According to the features of different low temperature thermal sources in mine, based on the statement of the heat pump principle, the paper had a study on th e thermal sources pump technology of mine air retuning sources, thermal recovery technology of cooling water in the electric power plant and thermal recovery technolo gy of mine water.In combination with the multi form existed features of the mine low temperature thermal sources, a comprehensive utilization technology of the mine |o W temperature thermal sources was provided.The utilization effect in the mines of Jizhong Energy Group showed that the utilization of the mine low temperature thermal energy would have a wide application prospect.
